Circadian rhythm in reflex thresholds may require timed testing in pain research; leaves open implications for clinical practice.
Do RII and RIII flexion reflex thresholds exhibit circadian variations in healthy male volunteers?
Human flexion reflexes (RII and RIII) exhibit significant circadian rhythmicity, with lowest thresholds in the early morning and highest at midnight, independent of beta-endorphin levels.
Sandrini et al. (1986) studied this question.
